Claims (1)

Способ производства бесшовных труб из малоуглеродистой стали, включающий внепечную обработку стали, горячую деформацию и двухкратную закалку, отличающийся тем, что после выплавки осуществляют продувку стали в ковше аргоном и обработку синтетическими шлаками, а после горячей деформации и охлаждения на воздухе проводят закалку из аустенитной области (Ac3 + 50oC), промежуточный нагрев до температуры 550-600oC, правку, охлаждение на воздухе, повторную закалку из межкритического интервала (750-830oC) и дополнительный нагрев до 600-700oC.A method for the production of seamless pipes from mild steel, including after furnace treatment of steel, hot deformation and double hardening, characterized in that after smelting, the steel is purged with argon and treated with synthetic slags, and after hot deformation and cooling in air, they are quenched from the austenitic region ( Ac 3 + 50 o C), intermediate heating to a temperature of 550-600 o C, dressing, cooling in air, re-quenching from the intercritical interval (750-830 o C) and additional heating to 600-700 o C.
